The defects in this device are inthat 50 of the brick; also to cause said supporting the end of the baris not, so to say, suffi- 10o ciently retarded to prevent the aforesaidbreaking of the clay at the bottom of the cutoff while the latter isbeing effected, and, secondly, in that the position the roller isrequired to occupy is such that it is struck by each of the cut-offwires in the course of the rotation of the cut-off belt or wlieell Thisinvention, which will now be described, fully obviates the aforesaiddefects which interfered with the perfect operation of the ma chine.

Referring again to the drawings, F is avertically-sliding plate locatedunder the advancing clay bar X about the distance of half the length ofa brick,'or in front of the point of complete severance of the bar, asseen clearly in Fig. 1, so that when the brick m is about to be entirelyout off it is supported by said plate, and, being about balanced, it hasno tendency to drop and break off. The plate is made with a flat top andbeveled or dropping edge toward the cut-off, as shown, so as to insurethat the end of the clay bar will properly strike and slide upon theplate. The friction of the clay upon the surface of the latter holdsback the projecting end, thus insuring the coherence of the yetunsevered part of the clay on the line of cut-off, so that when the wirereaches near the bottom of the bar the almost-severed end is preventedfrom being moved or jumped forward by the final force of the wire as itcuts through. In this way the heretofore breaking off or raggin'g of thelower edge of the brick is obviated. It is necessary that this plateshould be dropped or moved out of the way of the wire; otherwise itwould be struck by the latter as the cut-off wheel A, which carries theseries of wires, continues in its rotation. The top of the plate mustalso be nicely adjusted to the line of the under side of the clay bar. Acombination of mechanism will now be described,although it is hereremarked that the invention is not confined to the particular mechanismshown.

The plate F WOlkS in a guide-box, G, which is secured to the frame It.To its lower extremity is pivoted one arm, K, of a rock-lever on the endof shaftj, journaled in brackets e on the under side of frame It. On astud, e, projecting from the other arm, K, of said le- 'ver at aboutright angles thereto, is pivoted a rod, J, made in two parts-one witharighthand and the other with aleft-hand screwthread-with an adjusting-nut, n, and setnuts 77/, whereby the length of the rod may bereadily shortened or lengthened at pleasure. The upper portion of saidrod is flattened, and extends through a guide-slot, 01 in an angle-bracket, O, that is bolted to the side of the frame. A spring, S,connects the projecting ends of the fixed bracket ()and the arm K of therook-lever, the stress of the spring tending to draw up the said arm,and consequent'y odepresstheslidi *gsupportingplate F. A roller, r, isjournaled on the free end of rod .T, which roller rides upon the edge ofa circular disk, P, upon the shaft a a, that bears the cut-off wheel andbelt and tappetwheela which shaft is journaled in abort, q, upon thestandard q Fig. 2. Said diskis provided with depressions T, with roundedends, the number of which depressions and intervening elevations, T,respectively, s equal to that of the cut-off wires. The posltion ofroller 0" is such that it rides against the edge of the disk, being heldthere by the stress of the spring S. \Vhen the roller is riding upon theelevations of the disk, the plate F is retained in the position where 1tperforms its function of supporting the projecting ends of the clay bar;but as the disk continues its rotation the spring causes the roller toenter the depressions, and obviously at the same time the arm of thelever is raised up, and by the sequence hereinbefore described the plateis drawn down out of the way of the cutoff wire, and is then held asufficient time (regulated by the length of the depression) until it isagain elevated by the roller riding upon the elevated portion of thedisk. It will of course be understood that the arrangement of thedevices is such that the raising, retaining, and dropping of the slidingplate shall successively occur and continue at and during such intervalsas will effect the purposes of the invention.

In the drawings one of the wires has just completed the cutting off of abrick from the bar of clay. The roller 1' is about to drop into adepression upon the cam-disk, which occurring, the plate will be droppedand the brick be permitted to descend flatly upon the offbearing-belt.

Having thus described the invention, that which is claimed as new, andfor which Letters Patent are desired, is

1. In a brick-machine of the class recited, the combination, with thecontinuously-moving belt E and the rotating cut-off device arranged withrelation thereto, substantially as shown and described, of the plate forsupporting and retarding the advancing end of the bar of clay while abrick-length is being severed therefrom, said plate being locatedbetween the point of severance and delivery beyond said belt,substantially as described.

2. In a brick-machine of the class mentioned, the combination, with therotating cut-off devices, of the supporting-plate located with relationto the point of severance of the clay bar, as shown and described,together with mechanism, such as shown and described, for bringing andretaining the plate in position to support the end of said bar and formoving the same away from such supporting position out of the path ofthe cutolf wires, substantially as and for the purpose set forth.

3. In a brick-machine of the class mentioned, the combination, with therotating cut-off devices, of the vertically-sliding plate locatedrelatively to the point of severance of the clay bar, as shown anddescribed, the rocklever, the rod, the bracket, the spring, and the diskhaving the elevations and depressions, all constructed and adapted tooperate substantially as and for the purpose set forth.

4. In a brick-machine of the class mentioned, the combination, with therotating cut-off devices, of the belt for carrying the clay bar, theoffbearing-belt with its surface below the said carrying-belt, thesupportingplate located with reference to the point of final severanceof the clay bar, as shown, together with the mechanism for elevating,depressing, and retaining said plate, all constructed and adapted tooperate substantially as and for the purpose set forth.

5. In a brick-machine of the class mention ed, the combination, with therotating cut-off devices, of the vertically-sliding plate locatedrelatively to the point of severance of the clay bar, as shown anddescribed, the rocklength, the bracket, the spring, and the disk havingthe elevations and depressions, all constructed and adapted to operatesubstantially as and for the purpose set forth.

6. In a brick-machine of the class mentioned, the combination, with therotating cut-off devices, of the sliding plate located with relation tothe point of complete severance of the clay bar, as shown, therock-lever, the rod, the disk having the elevations anddepressions,andmeans for holding the free end of said rod in contactwith the disk by a yielding force, substantially as and for the purposeset forth.
